Abstract
A series of Bi3+ and/or Eu3+ doped LiGd5P2O13 (LGPO) were synthesized via a solid state reaction. In the LiGd5P2O13 lattice, Bi3+ shows a broad bluish-green emission around 500 nm and Eu3+ exhibits typical f-f red emissions. Based on the Bi3+ → Eu3+ energy transfers, the luminescence colors can be tuned from bluish-green to orange by altering the Bi3+/Eu3+ ratio. Under the 290 nm excitation, the sample with optimal composition of LGPO:0.1Bi3+,0.01Eu3+ exhibits a white light emission with a CRI of 82 and a CCT of 4250 K. The energy transfer mechanism from Bi3+ to Eu3+ in the LiGd5P2O13 host was ascribed to the dipole-dipole interaction.
